Ngophuhliso olukhawulezayo lweeselfowuni, i-elektroniki, amashishini onxibelelwano, ukuqhuba ngokuzimeleyo, njl.njl., ukuya kuthi ga kumlinganiselo omkhulu, kukhuthaze ukukhula okuqhubekayo kunye nokukhula okukhawulezayo kwenkqubo. PCB ibhodi ishishini. Abantu baxhalabele umgangatho, inani leeleya, ubunzima, ukuchaneka, kunye neemfuneko zemathiriyeli, imibala, kunye nokuthembeka nazo ziya zinyuka ngokunyuka.

Kukwangenxa yokhuphiswano oluqatha lwamaxabiso emarike, kwaye ixabiso lezinto zebhodi yesekethe yePCB likwakwimeko ekhulayo. Ukuze kwandiswe ukhuphiswano olungundoqo kwishishini, baya besanda abavelisi abakhetha ukuhoya imarike ngamaxabiso aphantsi. Nangona kunjalo, emva kwala maxabiso aphantsi kakhulu, ahlala efunyenwe ngokunciphisa iindleko zempahla kunye neendleko zokuvelisa. Ngale ndlela, umgangatho webhodi yesekethe yePCB ngokwayo ayinakufikelelwa.

Ke ngoko, amacandelo ebhodi yesekethe yePCB adla ngokuthanda ukuqhekeka (ukuqhekeka), kulula ukukrazula, (okanye imikrwelo), ukuchaneka kwayo, ukusebenza kunye nezinye izinto ezibanzi azikho kumgangatho, ezichaphazela kakhulu ukuthembeka kwesekethe yePCB kamva. ibhodi. Kufuneka kungqinwe ukuba isigwebo sitshiphu kwaye asilungile. Isenokungabi ntle, kodwa IiMpahla ezilungileyo mazingabizixabiso eliphantsi bubungqina bentsimbi. Ejongene neebhodi ezahlukeneyo zesekethe PCB kwimarike, kukho iindlela ezimbini ukwahlula umgangatho iibhodi PCB wesekethe; indlela yokuqala kukugweba ukusuka kwinkangeleko, kwaye enye ivela kwibhodi yePCB. Ijongwa ngokweemfuno zayo zokucaciswa komgangatho.

Imiba ephambili yokuchonga iibhodi zesekethe zePCB:

Okokuqala: ukwahlula umgangatho webhodi yesiphaluka ukusuka kwimbonakalo

Kwiimeko eziqhelekileyo, ngaphandle kwebhodi yesekethe ye-PCB inokuhlalutywa kwaye igwetywe yimiba emininzi yembonakalo;

1. Ukukhanya kunye nombala.

Ibhodi yesekethe ye-PCB yangaphandle igqunywe nge-inki, kwaye ibhodi yesekethe inokudlala indima yokugquma. Ukuba umbala webhodi awukhanyisi, kwaye kukho inki encinci, ibhodi yokufakelwa ngokwayo ayilungile.

2. Imigaqo esemgangathweni yobungakanani kunye nobukhulu beebhodi zeesekethe zePCB.

Ubukhulu bebhodi yesiphaluka buhluke kwibhodi yesekethe eqhelekileyo. Abathengi banokulinganisa kwaye bajonge ubukhulu kunye neenkcukacha zeemveliso zabo.

3. Ukubonakala kwe-welding seam yebhodi yesekethe ye-PCB.

Ibhodi yesekethe inamacandelo amaninzi. Ukuba i-welding ayilungile, iinxalenye zilula ukuwa kwibhodi yesiphaluka, eya kuchaphazela kakhulu umgangatho we-welding webhodi yesiphaluka. Imbonakalo ilungile. Kubaluleke kakhulu ukuchonga ngononophelo kwaye ube nojongano olunamandla.
